Scientific paper

We carry out the first full 3D, time-dependent numerical MagnetoHydroDynamic modeling of the interplanetary environment of close-in planets, as well as a space weather event on close-in planet. In the simulations, we use observed parameters of the HD189733 system. Our simulations reveal a unique interaction between the planet and the corona, as well as unique CME-magnetosphere interaction that can deposit large amount of energy in the planetary atmosphere. We discuss the consequences of such interaction in the context of planetary magnetic shielding, planetary atmosphere erosion, as well as planet habitability.
